In respect to the Black Lives Matter movement, Caltech Astro Outreach postponed this online public lecture originally scheduled for Friday, June 5th 7:00PM PDT. We do not want to create a distraction from this powerful moment for our country, when attention is better focused on addressing racial inequalities and injustices in our society. We are tentatively postponing our lecture until Friday, June 12th at 7:00PM PDT, but we will reevaluate this again this week. - Caltech Astro
